Gathering Oysters by Submarine 



A peaceful occupation at which the submarine is so efficient 

 that it promises to revolutionize the entire shellfish industry 



When traversing a good bed the submarine will suck up five thousand bushels of oysters in 

 an hour, leaving the bed clean-swept. It is not diverted from its course by wind or tide 



THE submarine is primarily a destroyer. 

 For the most part its inventors 

 thought only of blowing up ships, 

 notwithstanding the dramatically success- 

 ful trip of the Deutschland. Probably the 

 only inventor who believed in its peaceful, 

 industrial possibilities from the very be- 

 ginning was Simon Lake. He has sug- 

 gested the use of the submarine for polar 

 exploration, for ferrying supplies across ice- 

 bound rivers, for seeking sunken treasure, 

 and for digging oysters. We have already 

 pictured his transatlantic submarine freight 

 carrier — an older invention than the Deutsch- 



land — and on this page we illustrate his 

 submarine oyster gatherer. 



Preliminary experiments have demon- 

 strated to Mr. Lake's satisfaction that 

 when the submarine is at the bottom of the 

 ocean, the oysters can be sucked up into it 

 on the vacuum cleaner principle. When 

 traversing good ground, the submarine 

 will suck up five thousand bushels of oys- 

 ters in an hour. This means that in one 

 hour a mass of oysters will be collected 

 which, if compactly piled in a cylinder one 

 foot in diameter, would require a cylinder 

 one and three-quarters mile long to hold it.
